“The medical reports suggest that they are in real danger,” a statement signed by three reads. “We call on them to end their fasts before irreparable damage is done to their bodies.”

Ali started his hunger strike on August 1. He is demanding that his father and jailed Bahraini opposition leader Hassan Mushaima be granted access to proper health care, family visits and reading materials.

Last week, Zainab, whose father, Abdulhadi Al-Khawaja is another opposition figure and human rights defender imprisoned in the Gulf kingdom, announced that she was joining Ali’s hunger strike.
